Never measured the prop height, but the engine was a 10:1 compression 540 with ported and polished Patriot aluminum heads, dart intake, and a 1090 dominator. Crane 638 lift roller cam from Teague. Ran great. In another hull, eliminator/HTM, would have flew! Alittle disappointing only 74 from almost 700 HP!!!!!!!The boat handled rough water pretty well for what it was though. Never had a problem with the bravo, but I was very nice to it out of the hole, torque and weight of the boat made me nervous!!
